An angry Mark Webber branded Romain Grosjean a "first-lap nutcase" and intimated the Frenchman should receive another race ban after his Japanese GP was wrecked by the Lotus driver.

Just three races on from receiving the first race suspension in Formula 1 for 18 years for causing a start-line pile-up at Spa, Grosjean was involved in his eighth first-lap incident of the season at Suzuka when he punted the back of Webber's Red Bull as the field navigated the first two corners.

The contact spun Webber onto the grass, and prompted an unscheduled visit to the pits at the end of the lap for repairs. After battling back to finish ninth at the chequered flag Webber expressed his considerable ire with Grosjean.
